Reprogramming Autoimmune Immunity via Mitochondrial Quality Control: Mechanisms, Biomarkers, and Windows for Intervention. (from Rheumatology/Autoimmunity)
Chen Xiao; Ding Jie; Meng Liu-Qing; Li Shu-Fang; Chen Yong β International immunopharmacology 2026
Score: 7/10 | Pathways: cGAS-STING, NLRP3, ISG15-mitophagy, treatment-target, NF-kB-NLRP3-priming
This review directly discusses mitophagy/mtDNA-driven cGAS-STING-IFN-I amplification and NLRP3 hyperactivation as autoimmune drivers, mirroring the SAMHD1 A565T mitochondrial-interferon mechanism and proposing biomarker/treatment windows analogous to JAK inhibitor or MCC950-style interventions relevant to this family's phenotype.

Adipose-cartilage communication via EV-Mito-mtDNA signaling promotes osteoarthritis progression. (from Orthopedics/Rheumatology (osteoarthritis and obesity-adipose biology))
Gu Cheng; Liao Fawei; Kong Ganggang; Yin Shiyi; Jiang Yifei β 2026
Score: 7/10 | Pathways: cGAS-STING, mito-ROS-NF-kB, treatment-target
Demonstrates mtDNA (via EV transfer) activating cGAS-STING to drive inflammation and senescence, directly paralleling the BLUE loop (VDAC1-mtDNA-cGAS-STING-IFN) mechanism central to the SAMHD1 model, with therapeutic inhibition data.

Combined MEK1/2 and Autophagy Inhibition Suppresses Tumor Growth via STING-Mediated Type I Interferon Response in iCCA. (from Oncology (hepatobiliary cancer/MEK inhibitor pharmacology))
Sun Chengqiang; Gao Zheng; Dong Enfu; Ding Liangxia; Feng Shanru β Cancer science 2026
Score: 6/10 | Pathways: cGAS-STING, mTOR-lysosomal, ISG15-mitophagy, treatment-target
Demonstrates that autophagy/mitophagy suppresses cGAS-STING-TBK1 type I IFN signaling and that combined inhibition unleashes IFN-I output, directly modeling the mitophagy-IFN crosstalk (BLUE/RED loops) central to SAMHD1 pathology, though in an oncology (iCCA) rather than SAMHD1 context.

Neonatal Reversible Aortic Constriction Mice Model Unlocks Distinctive Footprints of Young Heart Recovery. (from Pediatric cardiology/cardiac surgery)
Huang Longming; Luo Kai; Zhang Xinjie; Zeng Guowei; Chen Bo β 2026
Score: 6/10 | Pathways: cGAS-STING, ISG15-mitophagy, treatment-target
This paper demonstrates the mtDNA-cGAS-STING pathway driving cardiac remodeling and shows mitophagy/urolithin A suppress STING activation, mechanistically paralleling the BLUE/RED loops in the SAMHD1 model and offering relevance to the cardiomyopathy/mitochondrial-cardiac phenotype tracked in the family, though it lacks any SAMHD1 connection.

Uracil-DNA glycosylase 1 mitigates acute kidney injury inflammation by maintaining mtDNA homeostasis (from Nephrology)
xiaohui Liao; Wang Chunxia; Tang Wei; Xie Pan; Wang Yuting β 2026
Score: 6/10 | Pathways: cGAS-STING, POLG-mtDNA, NF-kB-NLRP3-priming
Demonstrates mtDNA damage/leakage driving cGAS-STING inflammatory signaling in acute kidney injury via UNG1/SSBP1-mediated mtDNA repair, mechanistically parallel to the POLG-stalling/ox-mtDNA/cGAS-STING loop central to SAMHD1 A565T pathology though in a distinct disease context.
DOI: 10.21203/rs.3.rs-10469724/v1
Single-cell Unperturbed Activation Profiling by mass cytometry captures in vivo immune signaling in SLE. (from Rheumatology/single-cell mass cytometry biomarker methodology)
Burns Marie; Ostendorf Lennard; Abbas Amro; Ferrara Sebastian; Hirseland Heike β Frontiers in immunology 2026
Score: 5/10 | Pathways: JAK-STAT, treatment-target, clinical-phenotype
SLE study demonstrating type I IFN-driven pSTAT1/pSTAT3 signaling and baricitinib (JAK inhibitor) treatment monitoring is mechanistically relevant to the RED IFN-JAK-STAT pathway and JAK inhibitor therapeutics in the SAMHD1 interferonopathy model, though it does not involve SAMHD1 directly.

Leukotrichia: A comprehensive review of follicular depigmentation. (from Dermatology)
Iamsumang Wimolsiri; Kositkuljorn Chaninan; Leerunyakul Kanchana; Sakpuwadol Naw β The Journal of international medical research 2026
Score: 4/10 | Pathways: poliosis-neural-crest, clinical-phenotype
This dermatology review on leukotrichia/piebaldism/Waardenburg-associated follicular depigmentation is tangentially relevant only insofar as it illuminates neural crest melanocyte biology underlying the family's tracked poliosis/silver-streak phenotype, with no direct SAMHD1 or interferon-mitochondrial pathway content.
DOI: 10.1177/03000605261483177
ZBP1 in Neuroinflammation and Neurodegeneration: Z-Nucleic-Acid Sensing, RHIM Signalling and Therapeutic Targeting. (from neurology/neuroimmunology)
Θerban Matei; Toader Corneliu; Covache-Busuioc RΔzvan-Adrian β 2026
Score: 4/10 | Pathways: cGAS-STING, clinical-phenotype
ZBP1 senses oxidized mtDNA and self nucleic acids to trigger RIPK/MLKL inflammatory pathways in neuroinflammation, an innate-immune sensing mechanism parallel to but distinct from SAMHD1/cGAS-STING axis with only indirect relevance to the AuDHD/ME-CFS neuroinflammatory phenotype.
